LTC2630HSC6-LZ10

Overview

The LTC2630HSC6-LZ10 is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 4.096V and operates from a single 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Power-on reset options include zero-scale or mid-scale initialization. Supply current is typically 200µA at 5V with internal reference.

Feature Summary

• 10-Bit Resolution with Integrated 4.096V Reference
• Rail-to-Rail Output Buffer Guaranteed Monotonic
• 3-Wire SPI/MICROWIRE Interface (Up to 50MHz)
• Power-On Reset to Zero-Scale (LZ Suffix)

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's official documentation to ensure correct resolution, temperature grade, and power-on reset configuration. Confirm that the SC70 package dimensions match the design constraints. Check for lead-free compliance status if required by local regulations.

Selection Notes

Select this component when a compact, single-channel DAC with high accuracy is required. The H-grade indicates an automotive temperature range (-40°C to 125°C). The LZ suffix ensures the output resets to zero upon power-up. Ensure the system supply voltage falls within the 4.5V to 5.5V range required for the 4.096V full-scale option.

Part Context

This part belongs to the LTC2630 family of single-channel DACs. Other variants in the family offer different resolutions (8, 10, 12 bits), temperature grades (C, I, H), and full-scale voltages (2.5V or 4.096V). The SC70 package allows for space-constrained designs compared to larger QFN or MSOP packages found in quad-channel versions like the LTC2635.

Replacement Considerations

Direct replacements within the same family include LTC2630ISC6-LZ10 (Industrial temp) or LTC2630CSC6-LZ10 (Commercial temp). For higher resolution, consider LTC2630HSC6-LZ12. For quad-channel applications, the LTC2635 series offers similar functionality in larger packages.
